Correct Answer: B

Rationale: The correct answer is B. Clients should eat a snack when their blood glucose level is low, typically below 70-100 mg/dL, not when it is high. Eating a snack when the blood glucose level is above 200 mg/dL can exacerbate hyperglycemia. Choice A is correct as checking blood glucose levels regularly is important in managing diabetes. Choice C is also correct as adherence to prescribed insulin therapy is crucial. Choice D is incorrect as physical activity can help lower blood glucose levels, especially when they are above the target range.

Correct Answer: A

Rationale: In a client with pericarditis, the priority finding is a paradoxical pulse. This is a crucial sign of cardiac tamponade, a life-threatening complication of pericarditis where fluid accumulates in the pericardial sac, causing compression of the heart. A paradoxical pulse is an exaggerated decrease in systolic blood pressure (>10 mmHg) during inspiration. Prompt recognition and intervention are essential to prevent hemodynamic instability and cardiac arrest. Dependent edema (choice B) is not typically associated with pericarditis. Pericardial friction rub (choice C) is a common finding in pericarditis but does not indicate the urgency of intervention as a paradoxical pulse. Substernal chest pain (choice D) is a classic symptom of pericarditis but is not as critical as a paradoxical pulse in the context of assessing for complications.

Correct Answer: A

Rationale: Facial flushing is a common symptom of early dumping syndrome, which occurs when food moves too quickly into the small intestine. This rapid movement triggers the release of vasoactive peptides causing vasodilation, leading to facial flushing. Syncope (choice B) is not a typical finding in early dumping syndrome. Diaphoresis (choice C) and bradycardia (choice D) are also not characteristic symptoms of early dumping syndrome.

Correct Answer: C

Rationale: The correct answer is to limit saturated fat intake to 7% of daily calories. This recommendation is crucial for clients with hypertension to lower cholesterol levels and promote heart health. Choice A, limiting sodium intake to 4 grams per day, is important for hypertension but not the best recommendation compared to limiting saturated fats. Choice B, limiting protein intake to 80 grams per day, is not a primary dietary concern for hypertension. Choice D, limiting fluid intake to 1,500 mL per day, is not a standard recommendation for hypertension management.

Correct Answer: A

Rationale: The correct answer is to administer calcium gluconate. In hyperkalemia, the priority is to protect the heart from potential complications like arrhythmias. Calcium gluconate is the first-line treatment as it stabilizes the cardiac cell membrane. Insulin (Choice B) and sodium bicarbonate (Choice C) can be used in conjunction with other treatments to shift potassium into cells, but calcium gluconate is the priority. Administering a diuretic (Choice D) is not the primary intervention for hyperkalemia and can even worsen the condition by reducing potassium excretion.
